Definitions

  • the present invention relates to apparatus generally known as a calender for the heat treatment of material such as, sheet and brous material having very little thickness and, more particularly, but not exclusively, to apparatus for carrying out the process commonly called the thermo-impression of fibres.
  • This process consists of exposing a paper which has been previously impregnated with colouring, chosen for example, among those colourings called dispersed or plasto-soluble to a suitable temperature, in the order of 120 C., for a given time, in relation to the intensity of the shade to be obtained, for example, a half to two minutes, in such a way that the colouring, by evaporation or sublimation is fixed to the material, for example, fabric to be tinted.
  • colouring chosen for example, among those colourings called dispersed or plasto-soluble
  • the heating effect has been obtained by passing products between a revolving drum or calender and a xed plate made as a segment of a cylinder enveloping the calender.
  • Rigid shapes are also very diiiicult to apply to the drum and, as a result, there is frequent evidence of the treated products being crushed, to a varying degree, in relation to the thickness of the said treated product.
  • This adhesive force also creates a relative displacement of the paper and of the product thus marring the final result.
  • the known method of heating the calender does not enable a uniform temperature to be obtained on the calender.
  • An object of the present invention is to minimise all the above-mentioned drawbacks by means of an improved apparatus for the heat treatment of sheet and fibrous material comprising a rotatable cylindrical drum heatable to a predetermined temperature and means for rotating the drum, which is characterised by an endless belt for applying the material to be heat treated to the cylindrical surface of the drum, said belt having a linear velocity which is substantially equal to the angular velocity of the cylindrical surface of the drum, the belt encompassing the major part of the drum.
  • FIG. l is a diagrammatic side view of an apparatus for the heat treatment of sheet and fibrous products
  • FIGS. 2, 3 and 4 are details of the apparatus of FIG. 1 showing guiding rollers for an endless belt and their means of mounting;
  • FIG. 5 is a detail of a centering device for the endless belt
  • FIG. 6 is a detail of a braking device for the winding and/or un'winding of the bands of material to be processed by the apparatus of FIG. 1;
  • FIGS. 7 and 8 are diagrammatic sectional views illustrating methods of heating a drum of the apparatus of FIG. l.
  • an apparatus for the heat treatment of sheet and fibrous products for example, a thermo-impression process in which paper carrying a design and fabric on which the design is to be transposed comprises a cylindrical heating drum 1 on which the fabric 2 and the special paper 3 are applied by an endless belt 4.
  • the drum 1 can be heated by different means such as steam, an oil bath, electrical resistance, thermic uid, gas, etc.
  • the drum 1 can be placed in an oven or in a heated chamber 5. Alternatively, or as a supplement to the chamber 5 a preheating device 6 can be coupled or the cloth heated.
  • drum 1 can be heated by the circulation of pressurised heated oil.
  • the oil enters the drum 1 by duct 7 (see FIG. 7) inside shaft 8 of the drum 1 and flows between side plates 9 0f the drum 1. It then circulates through the passageway 10 defined vby the spaced sides of two concentrically mounted shells 11 and 12 forming the drum 1 and exits via duct *13 in the inside of the opposite ⁇ side plates of the drum 1 into the shaft 8 of the drum 1.
  • this method of heating drum 1 suffers from the disadvantage that, a slight difference in temperature is established between one end and the other of the drum 1.
  • the drum 1 is produced by the assembly of three concentric tubes 11, 12 and 14 (see FIG. 8).
  • the heated iiuid enters the shaft 8 via duct 7 and passes through duct 9 at one side of drum 1. It then passes into duct 10" defined by shells 11, .'12 and flows along the width of the drum 1.
  • drum 1 The major part of drum 1 is covered by an endless belt 4 which forms part of a conveyor arrangement including guide rollers 15, a driving roller 16 and an adjustable tensioning roller 17.
  • driving roller 16 moves the belt 4 which by frictional engagement with drum 1, rotates drum 1.
  • the guide rollers and the tensioning roller 17 are arranged such that any displacement of the tensioning roller 17 determines a variation in length double to the trajectory of the belt 4.
  • tensioning roller 17 has journals 18 ⁇ which are each mounted in a movable sliding bearing (not shown). The sliding of the bearings is controlled by two jacks 19 working at each end of tensioning roller 17 but having all their movements synchronised in order to avoid any non-alignment of the bearings.
  • the synchronising device consists of two sets of pinions 20 and racks 21. Each of the racks 21 is integral with a bearing and engages a pinion 20. Pinions 20 are keyed onto the same shaft 22. Movement of the bearings is provided by jacks 19, enabling the pressure of the belt 4 on drum 1 to be adjustatbly varied. An adjustable reducing valve (not shown) for compressed air leads to the jacks 19 and allows this pressure to be adjusted, from 0 to 200 grams per square centimeter.
  • the driving roller 16 is adjustable and can take up different positions between those shown in chain dotted lines and in broken lines on FIG. 5.
  • This displacement is operated by a screw and nut or worm wheel system (not shown), the power unit of which is operated by switch 23.
  • a timing device is provided in order to avoid any accidental operation. If belt 4 is excessively out of centre, switches 24 and 25 are operated which bring the whole apparatus to a halt.
  • rollers 15, 16 or 17 have their journals 26 and 27 (see FIGS. 2 to 4) mounted in bearing plates 28 the dismantling of which allows a space 29 large enough to permit the rollers 15, 16 or 17 to be removed.
  • the rollers 15, y16 or 17 are held by means of sleeves 30 and 31 which engage the journals 26 and 27 (see FIGS. 2, 3 and 4).
  • the apparatus includes means for feeding the basic materials 2 and 3 to be treated, for the collection of the finished product 2' and for the paper which supports the design being transferred.
  • the feed device for the fabric comprises an unwinding device 32 rotatable by a motor.
  • a compensator 39 consisting of a pulley 40 pressing against the base of a loop of fabric 2 and being displaceable vertically to take up the differences in length of the fabric between the feed device and the drum 1. These differences are related to the variation of speed between the fabric supply via the unwinding device 32 and the take-up by drum 1.
  • the travel of this pulley 40 is limited by two stops consisting of micro-switches (not shown) which predetermine the stop or start of the unwinding device 32.
  • the printed fabric 2' runs over another compensation device 39, similar to the previously described compensator, before being made into rolls 41 by a winding device 42.
  • This winding device is operated by a cylinder being driven by motor 33.
  • the special paper 3 supporting the design to be transferred is supplied by a roller 43, the journals of which are placed in slots in a rack (not shown) on which a second reserve roll 43 is mounted, enabling a continuity in the feed of paper 3 from drum 1 to be obtained.
  • the paper 3 is stretched by means of an adjustable brake (FIG. 6).
  • This brake comprises a toothed friction disc 34 made integral with a framework and against the faces of which the jaws 35 and 36 are pressed by the action of a compressible element 37 adjusted by means of a nut 38.
  • the paper 3" is immediately detached from drum 1 by means of an unwinding roller 44 on one side and a scraper 45. Next, it is brought up to a winding device 42.
  • This winding device is in the form of a cylinder driven by means of a clutch 33'.
  • the clutch 33 (FIG. 6) comprises the toothed friction disc 34 gripped by jaws 35 and 36 one of which, at least, is integral in rotation with the cylinder to be driven. The friction couple thus produced is able to be adjusted by turning the nut 38 altering the action of the intermediate compressible element 37.
  • the feed for the fabric to be printed can include an unwinding device for edging 46, by an edging guide 47 and similarly by a wiping bar 48.
  • Wiping lbar 48 can be made either in the form of a simple square bar, or, in the form of a bar having opposite threads at each end.
  • an apparatus for the heat treatment of sheet and fibrous material comprising a rotatable cylindrical drum Il'leatable to a predetermined temperature' :and means for rotating the drum, the improvement which comprises an endless belt for applying the material to be heat treated to the cylindrical surface of the drum, said belt encompassing the major part of the drum and having a linear velocity which is substantially equal to the angular velocity of the cylindrical surface of the drum, and a conveyor arrangement over which said endless belt passes, the conveyor arrangement comprising guiding rollers, and adjustable tensioning roller and a driving roller, movable sliding bearings for supporting the tensioning roller, jacks for engaging and moving the sliding bearings to adjust the position of the tensioning roller and a synchronising device to ensure correct alignment of the sliding bearings.
  • the synchronising device comprises two racks, each rack being integral with a sliding bearing, and two pinions each keyed to a shaft and each engaging a rack.
  • driving roller is adjustable between two positions each inclined to the rotational axis of the drum and extending on either side of a plane parallel with the axis of rotation of the drum.
  • thermo-impression process comprising a rotatable drum on which paper carrying a design and fabric on to which the design is to be transposed, are heated and means for rotating the drum, the improvement which comprises:
